Synthesis of (1S,4R)-4-isopropyl-1-methyl-2-cyclohexen-1-ol, the aggregation pheromone of the ambrosia beetle Platypus quercivorus, its racemate, (1R,4R)- and (1S,4S)-isomers

(S)-Perillyl alcohol was converted to (R)-cryptone (91.5-93% ee) in six steps, which was then treated with methyllithium to give (1S,4R)-4-isopropyl-1-methyl-2-cyclohexen-1-ol, the aggregation pheromone of the ambrosia beetle Platypus quercivorus. The racemic pheromone was also prepared by methylation of (±)-cryptone. Both (1R,4R)- and (1S,4S)-isomers (98% ee) of the pheromone were synthesized from the enantiomers of dihydrolimonene oxide.

Δ5-DEHYDRO-1-HYDROXYCARVOMENTHOLS FROM THE ESSENTIAL OIL OF CHENOPODIUM MULTIFIDUM

The most polar fraction of the essential oil of Chenopodium multifidum is made up of three p-menth-5-en-1,2-diols diastereoisomers.Their absolute configurations have been assigned by spectral methods and by hydrogenation to the 1-hydroxycarvomenthols of k
